James Price 128980f218 tint: Add support for workgroupUniformLoad
Accept any type in the intrinsics definition, and then manually
validate that there are no atomics in the type. Add manual E2E tests
for composite types.

Use the BuiltinPolyfill transform to implement it for all backends.

Update the uniformity analysis with special-case tags for the builtin.
